a chat with no chosen directory runs in the caller's own home

The default was DATA_PATH/<email>/general_chat_sessions, a dedicated directory so /chat
sessions formed their own Claude project group instead of cluttering the home. It is a sibling
of the home, and confineUserTree makes every sibling the platform's at 0700 because the others
are attachments and email_accounts. So it was unreachable for a member: the first live member
turn started there and every Bash call failed on its own working directory before doing
anything.

A per-member copy inside each home fixed the symptom and left two rules to remember. The owner
chose one rule instead — the account's own home, whoever they are — and accepted the trade
knowingly: /chat sessions now share a project group with anything else run from that home,
which was the reason the dedicated directory existed.

Removed rather than left dangling: getGeneralChatSessionsCwd, ensureGeneralChatSessionsCwd,
ensureMemberChatCwd, and general_chat_sessions from USER_DIRS so new accounts stop getting it.
Existing directories are untouched and their transcripts stay where they are — Claude groups by
cwd, so the owner's old /chat history remains under its own project slug rather than moving.

The UI labels move with it: the default group now reads "home" rather than naming a directory
that no longer has a role.

ChatIdentity keeps carrying both email and home. The pairing was justified in the comment by
general_chat_sessions being email-derived, which is now gone — but the distinction it encodes
is real (the email says who, the home says where), so the comment explains that instead.
